Our scientists have developed a new tool for improved wildfire prediction using machine learning (ML), as set out in a paper published on 1 April 2025 in Nature Communications.
ECMWF highlights two competitions on World Meteorological Day
ECMWF highlights two ambitious international competitions on the occasion of World Meteorological Day on 23 March: the AI Weather Quest on sub-seasonal weather forecasts and the 2025 edition of Code for Earth to develop innovative open-source software.
ECMWF to achieve fully open data status in 2025
ECMWF is bringing forward the full transition to open data by an entire year, to 1 October 2025, marking a significant milestone in its commitment to making weather data more accessible and impactful.
EarthCARE instruments working together to evaluate atmospheric models
Launched in May 2024, the EarthCARE satellite’s unique combination of instruments – a radar, a lidar, an imager and a broadband radiometer – will improve the modelling of clouds, aerosols and precipitation in a number of different ways.
Developing ECMWF’s seasonal forecast system
ECMWF’s seasonal forecasts are based on our medium-range forecasts but extend to seven to thirteen months. Stephanie Johnson has a key role in developing and optimising the seasonal forecasting system.
ECMWF’s AI forecasts become operational
ECMWF has taken the Artificial Intelligence Forecasting System (AIFS) into operations today, 25 February 2025, to run side by side with its traditional physics-based Integrated Forecasting System (IFS) to advance numerical weather prediction.
ECMWF takes leading role in Space for Early Warning in Africa
ECMWF is contributing to the EU-funded Africa–EU Space Partnership Programme that started in January 2025 by taking a leading role in the four-year Space for Early Warning in Africa (SEWA) component.
International Day of Women and Girls in Science 2025
To mark the United Nations' promotion of 'full and equal access and participation for women and girls in science', we invited some of our ECMWF colleagues to tell us more about their work. From improving weather forecasts to advancing climate research, their stories highlight the diverse contributions women make to science.
New 10-year ECMWF Strategy emphasises collaboration and machine learning
ECMWF’s new Strategy from 2025 to 2034 sets out anticipated progress in science, impact and organisation and people. It emphasises the need for collaboration and the future role of machine learning in weather prediction.
